Mock CCC '18 Contest 4 Senior

This is the fourth contest in a series of mock CCC contests produced by rpeng. Unlike with previous contests, the other contest-setters do not wish to affiliate themselves with this contest.

Much like the real CCC, you will have 3 hours to do 5 problems with full feedback. You may submit no more than 50 submissions per problem. Additionally, the scoreboard will be disabled during the contests.

To emulate CCC, we will be using real CCC problems.

This contest will not be rated. Please do not discuss the contest until after the contest period is over.

CCO cutoff using this contest would have been a 60.

    Is there something wrong with test case #4 for problem #1?

      hint: beware of pluralization :)

        I found test case #4 for problem #1 from the official site and it also uses incorrect pluralization.

      The problem has been solved outside of contest a couple hundred times (not including the real CCC), so the test cases are most likely correct.
